I was wondering if you guys could tell me if the O2 sensors on the exhaust system are easy to get to on our cars. And is there any special way/tool to remove them and are they usually hard to break free?

Just wondering. I want to replace mine because my car is getting really crappy gas mileage. I have already replaced my gas cap,my cold air intake has this really old crappy filter on it. I have a new K&N coming in for that. I had a tune up not too long ago.

Should I have my timming check? My engine runs great and is so quiet too I just cannot figure it out.

I took a 30 minute drive the other day and burned about a half a tank of gas doing it and I don't ever see fuel leaking anywhere??


Sorry for so many questions guys but I'm stumped!!!!

Thanks

Jason
